    Interesting. Haven't tried it yet myself, but some folks on the AMD forum said it helped boot time a bit. Use at your own risk of course. :)

    "Subject: Microsoft claims Longhorn will be, er, faster

    The only reason why its faster is they added a superfetch feature to the prefetcher. If you look at the key:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\Prefetcher

    you will notice in windows xp

    EnablePrefetcher = 3 and you will notice in windows longhorn
    EnableSuperfetch = 1

    Well, guess what? You can put the EnableSuperfetch = 1 in windows xp and get the same speed.

    Wow, Microsoft just added a feature that was already there in xp."

    this sounds a little suspicious...sort of like if I put the value :[faster faster computer] and set that to a value of one it will speed my box

    any time there is a reg hack that improves performance and the default value is not set to optimum I am suspicous...why wouldn't ms set the value as best it could out of the box?

    anyway, if it's a worthless value the os won't see it, so I don't see a harm in giving it a go

    report back please

    regardless of how it works, would it be anything noticeable? I tried BootVis awhile back, but there have since been conflicting reports on the reliability of it's boot-time reporting.

    all bootvis does is the same thing xp's native optimization does every three days anyway

    What if you don't reboot every three days?

    I dunno, as I don't reboot very often. How about a way to increase WMP10 library load time. With a large library it takes a couple seconds to load.


    But that would make sense and actually be beneficial.

    And as a last rant, what does boot time actually prove anyway, that your PC needs to reboot often, but DAMN can it do it quick?

    heh, yeah right? Dude, why WMP? Use winamp, much less resources!

    I use both, but mainly WMP. So far as resources, with a gig of RAM it doesn't even dent it.

    I tried it on my test rig, did not notice any improvements so far. boot time is the same, loading apps and so on... i change it back to the org prefetch setting...

    I really don't see this being a noticeable speed gain feature. If indeed Longhorn, now Vista, will be faster, it is more than likely due to the different file system WinFS.

    Prefetching is a feature of the kernel. This "tweak" won't do anything on an XP system since the kernel doesn't recognize it. It's as good as adding a random DWORD entry into the registry called "OverclockCPUTo25GHz" and expecting magic to happen. :)

    Microsoft tweaks the NT kernel in each new OS. Prefetching was added to XP. It will be improved (i.e. Superfetch) in Vista. Simple as that.

    Dude, not true. When I put in a DWORD for "RunMacOSXonMyPCsinceAppleisSwitchingtoIntelBasedCPU's" woah, my computer reached out of the monitor and *slapped* me

    haha, thank god it's Friday :)

    And just to clear up any doubts, you can try examining the strings within ntoskrnl.exe. Here's what you get:

    Notice how there's nothing related to Superfetch in there? :)

    Shame on you, you didn't use "EDIT:". I saw your original post and it was missing most of that :) Haha, caught you!

    Hmmm, I'm sorry, but you leave me no choice. I'm going to connect to your machine, and create a new DWORD value called "DoNotLetUserDrinkatComputerBecauseSugarisbadforStickyKeys" and set the Hexidecimal value to FF

    You have been warned :mad:
